LsM/vA/s/r/ nemer Patented July 7, 1953 UNITED STATES i f- ADJUSTABLE CONVEYER FOR HARVESTER PICKUPS 9 Claims.

This invention relates toa harvesting machine and more particularly to a harvesting machine on wheels which is adapted to pick up cut grain or other harvested products and transfer the same to a. wagon or other storage container.

It is the object of the present invention to provide a harvesting device on wheels which includes a pick-up and conveying frame in conjunction with one or more other conveyors for transporting'the cut grain from the ground over the various conveyors and upwardly into a wagon or other storage medium. l

It is a further object of this invention to provide a pick up conveyor which is pivotally mounted upon the machine frame and which can be raised and lowered manually at its outer end to the desired extent.

It is a further object of this invention to provide a power transmission between the supporting shaft of one of the, wheels of the device and the pick-up conveyor mechanism whereby the latter is operated as the harvester device is moved over the ground.

It is a further object of this invention to provide a second elongatedloading conveyor which is suitably suspended from the frame of the device and which may be angularly raised and lowered with respect to said frame, and whichy may also be turned at an angle to said rst conveyor. j

These and other objects will be seen from the following specification and claims in conjunction with the appended drawings in which- Fig. 1 is a perspective view of the machine from the front end thereof.

Fig. 2 is a, perspective view thereof from one side and with the wheels and other parts removed.

Fig. 3 is a fragmentary plan view of a portion of the device; and

Fig. 4 illustrates the driving connection to one of the conveyors.

It will be understood that the above drawings illustrate merely a preferred embodiment of the invention and that other embodiments are contemplated within the scope of the claims hereafter set out.

vReferring to the drawings the harvesting machine includes a pair of supporting wheels I and 2 attached to the frame hereafter described. One of the wheels includes 'a rotatable shaft 3 upon which it is secured with said shaft being suitably supported and journaled upon the frameV element 1. A gear 4 is secured upon the shaft 3 and is in mesh with a pinion 5 mounted upon a 'l as shown in the drawings.

2 second supporting shaft 6 which shaft is also mounted and journaled upon the frame element The vframe for the. harvesting machine'includesv a pair of upright frame elements 8 anda longi-A tudinally spaced upright pair of frame elements 9 having respectively interconnecting their upper, ends'the cross pieces I0 and II.n Horizontal bars I2 which form a part of the drawing tongue of the device are positionedlupon opposite sides of the frame elements 8 and 9r in substantiallypar-l allel relation and are joined to `elements 8 and lSl by the connections I3 and I4.

The forward ends ofthe tongue converge to-v wards each other at I5 and terminateA in the2 closely spaced forwardvprojections I6 which are joined together by the spacer I1 as shownin Fig. 1. Rectangularly shapeddraw lbar I8. is' positioned between the forward ends I6 of the tongue I2-I5 and pivotally connected thereto by the bolt I9( at one end thereof. Parallel spaced plates 20 with attachment openingsZI are secured to the draw bar I8 providing a means of attachment of the .harvesting device to a tractor or other pulling mechanism.

v Spaced cross supports .22 and 23 span and interconnect the converging portions I5 of the tongue and an angle plate 24`is centrally secured upon said cross supports. The lupright frame 25 of circular `shape has a circular gear segment 25 thereon for cooperation with'a con? trol lever inr a manner hereafterl described.

As shown in Figs.' 1 and 2 there is provided a grain or vegetable pick-up conveyor which projects forwardly of the present harvesting Ydevice and which includes a pair of parallel spaced' supporting plates 26 `,whose inner ends are'pivotally mounted to the interior walls of the side frame 'Ito permit raising and lowering of the outer ends of said frame elements. Bearing sup-V` ports 28 project laterally from the outer endsl of the members 26 and the shaft 21 interconnects. the outer ends of the supporting plates 2liV and is journaled within thebearing vsupports 2 8.

Sprocket gear 29 is secured upon the shaft 2ll within the support26 and is in engagement with the continuous sprocket chain 3I. Similarly there is also a second sprocket gear 29 at the l opposite end ofthe shaft 21 positioned withinY lthe other side support 2S and which is also en-A gageable with a second continuous sprocket chain Y 3 I. rThe sprocket gears 30 engage the upper ends of the sprocket chains 3| and are suitably journaled upon the side frame .element 'I whereby both of the sprocket chains move in unison' ATENT OFFICE f within and between the conveyor side supports 26. The upper sprocket gears are mounted upon the rotatable shaft 6 which is driven by the pinion 5 thereon and which is in turn in mesh with the gear 4 on the rotatable wheel supporting shaft 3. Consequently rotation of the wheel I as the device is drawn along over the ground causes rotation of the sprocket chains 3I which are interconnected by the shaft 21 and the lower sprocket gears 29 to thereby effect a continuous movement of said sprocket chains during movement of the harvesting vehicle.

A plurality of parallel longitudinally spaced cross rods, such as the cross rods 32, 33, 34, and 36, are interposed between the sprocket chains 3| with their ends joined thereto for movement in unison. While ,in Fig. 2 there .are shown only the live cross rods, it is contemplated that these cross rods should be spaced throughout the entire length of the sprocket chains. A row of longitudinally spaced .ngers .31 .of predetermined length and .certain additional fingersoi shorter length 38 are arranged in -.a..longitudinal row'in .spaced relation upon each of the cross rods .32., 33, 34, 35 and 38,..for:illustration, and

are upon a slight angular inclination as shown in Fig. 2. The said sprocket-chains `3I andthe cross rods with their .fingers vare 4continuously movable `as the Wheels rotate .to therebyprovide a grain or vegetable pick-.up and conveying device. It is understood that the iingers 31 and .38 will .maintain the same inclination `upon .their respective cross rods "throughout ftheirmovement upon .the upper side-of .the .conveyor and will begin to yturn in aclockwise direction 'only as they round `the ends thereof.

A plurality of inclined parallel spaced .stationary .staves 39 are arranged Van-d .supported within the conveyor mechanism 'and there is mounted thereon a suitable cover 3.9 aportion of which is shown in Fig. V2 to prevent particles of the harvested product from dropping through the conveyor.

Plate .brackets 40 are secured towards the .outer ends of the conveyor `side .supports 26 .and .the lower ends of the .cable 4I .extend over the pulleys 42 .and are j'oinedlto said bracket-s with the .upper ends .of vsaidcalole :being joined to the controlarm 43 as atvpoints 42.

Control arm 43 with handle 44' is pivotal-ly mounted at 44 to the angle plate -24 upon .the tongue elements I5. 'Ihe -control arm 143 extends upwardly and has a release arm 45 pivotally joined theretoat 4.6.

{Ilhe :control bar 41 .depends :from release arm 4,5 and has a hook 48 at l:itslower end which :is joined Ato :a reciprocalshaft .'49 :whose lower :end is joined to and carries the ringer 'adapted for selective engagement within the gear vteeth 125" ofthe frame .element'25- Upward pivotal-movement of the release arm 45 disconnects the nger 58'from said gear teeth whereby the control arm 43 through its handle 44' may be pivoted about the point 44 to thereby draw up upon the cable 4I to ythereby effect an upward pivotal movement of the `pick-up conveyor and its side supports 26, inasmuch as the outer ends 'of said cable are joined to the outer ends of the conveyor side supports 26. Thus by'manipulating the control arm 43 theouter end of the .pick-up conveyor may be adjusted vertically with respect Ato Ythe `ground to the desired elevation.

Referring to Fig. 2 the harvesting machine. frame elements 9 include the lower Arearwardly extending frame elements 5I which are joined at their rearward ends by the cross beam 52.

A second elongated loading conveyor is provided upon the rear end of the device, which includes the parallel spaced frame elements 53 and 54 which are laterally spaced from a second pair lof frame elements 53 and 54 defining the supporting side 4walls of said secondary conveyor. The side walls are reinforced by theinterconnecting upright bars 55, y56 and 51 and suitable bearings 58 are supported upon the outer end of said conveyor upon opposite sides thereof for journaling and .supporting the transverse shaft Similar spaced bearings are arranged at the opposite inner ends of the conveyor frame elements 53-54 for supporting the rotatable conveyor shaft 6I there being spaced sprocket gears `6I) :secured adjacent opposite endsl of the shaftV 59 and similarly spaced sprocket gears 62 adjacent the opposite .ends of the `shaft 6 I.

`Suitable .sprocketfchains y83 interconnect the sprocket gears 69 and 62 within and upon oppo-p site sides .ofthe frame elements 53-54 and ,a plurality of cross Vloars4 are longitudinally4 spaced around the two .sprocket chains 63 with their .opposite .ends respectively joined thereto` for movement in -unison with said chains, A'

suitable vendless Vcover of canvas or .other materialextends around uthe shafts 59 and and is .secured .to the cross bars I64 which stiien'the same, to thereby provide .a suitableloadingcon-- veyor which operates lin conjunction with the grain or Vegetable pick-up vconveyor iirst described.

The upright brackets V6B .and :61 are secured upon opposite sides of the .conveyor frames `53 and .54 in spaced relation .and arranged towards the upper delivery end thereof .upon which are positioned two converging elongated guide .plates 68 between which the `harvested material iscarried by the conveyorelement l65.,.szaid plates beingl secured as at B9 to said brackets..

Parallel spaced forwardly .inclined side framesY 1.0 are pivotallyjoined atftheir lower ends to thel central cross plates 456 of theloading conveyor,4 and their upper ends are interconnected by the The central portion of `cross bar` 1I is secured to the end of lever 12, the latter becross bar 1 I.

ing pivotally mounted at 13 to the central supporting beam 14. Said beam isjfcentrally supported upon and pivoted vat 18 to the swivel 15A which isarranged centrally upon cross frame element II. The other end of the beam .14 terminates in the cylindrical portion 11 which is positioned and retainedpwithin the slot '18 'arranged at the upper ends of the upwardly inclined supporting legs 19, the lower ends of which are suitably anchored as at to the horizontal cross piece I 'IJ of frame element 8.

The reinforcing stay vbar '8| is `joined .at '82 to I The link 89 is mounted and supported upon they frame elements 19 by the bracket elements 9D and 9| whereby an intermediate portion of said link supports the outer end 11 of the beam 14 at point 92 maintaining the same within the slot 18 in the :Frame elements 119. However the link `89 may be removed 'to thereby .permit the end 11 lof the beam 14 to be dropped or.` drawn'downwardly so as to extend below the upwardly inclined frame elements 19.

The lateralV angle. iron 93 is secured to and projects from the frame element 8 -as shown in Fig. 1 and has secured thereto the arcuate gear segmentV 94 with gear teeth 95. The control arm 96 is pivotally mountedat 91 at its lower end toA the angle iron 93 and the upper end of the arm 916 has an operating handle 91. The'control trigger 98 isfpivoted at one end to said arm at 99 and has a 'depending tie rod |00 whose lower end engages the iinger-|.02which is adapted for selective registryr within 'the teeth 95 of thegearsegment 94, there being a suitable coil springv normally urging said finger downwardly relative to said teeth.

The operating link |03 Vis pivotally joined at |04 atv one end to the lower portion ofthe control arm 96, and the opposite end of said link is joined at |05 to the end of the beam 14 as shown .in Fig. 2. By this construction, once'the cylindrical end 11 is released by downward movement from the retainingslot 18, pivotal movement vof the control arm 96 through the link |93 will cause a swivel movement of the beam 14 below the frame element 19 and upon the swivel 15 on frame elements 9| v Thus the loading conveyor may be angularly turned with respect to the pick-up conveyor with the extent of the turning regulated by control arm 96.

The sprocket gear |01 is keyed upon the shaft 6 and is interconnected with the lsprocket gears |08, ||0 and ||2 by the sprocket chain |06. Thus rotative motion of wheel I turns the shaft 3 and thegear 4 thereon which in turn rotates the gear 5 to effect rotation of the shaft 6 and this shaftV drives the sprocket-gear |01 and the chain |06 connected therewith to thereby rotate the aforementioned sprocket gears |08, ||0 and The sprocket gear |08 is secured upon the transverse shaft |99 which is supported and journaled upon the rearwardly projecting frame elements 5|. A similar sprocket gear |08 is also provided upon an extension shaft |09 journaled and supported upon and under frame elements 5S- 54. to effect rotation of said extension shaft through a suitable universal joint ||8. Shaft 6| which drives the conveyor belt 65 by means of sprocket chains 63 is itself joined to said extension shaft |09. Sprocket gear |08 on shaft 109' joins sprocket gear 62 on shaft 6| by a sprocket chain |9 for rotating the same. y

The sprocket chain |06 passes underthe idler sprocket gear |||3 which is journaled upon the shaft supported upon the frame elements 5| and 52 as shown in Fig. 2. The sprocket chain is in driving engagement with the sprocket gear ||2 on the transverse rotatable shaft ||3 which carries sprocket gear ||4 adjacent thereto and a similar sprocket gear, not shown, upon its opposite end. The shaft |3 and the sprocket gears |4 thereon are adapted to effect movement of the intermediate upwardly inclined conveyor belt ||6, whose lower end extends adjacentand below the upper end of the pick-up conveyor lat the forward end of the machine.

The shaft ||3 is journaled at its opposite ends within suitable bearings at the upper ends of the inclined frame-l I6 which is secured to the frame elements 9 on opposite sides andA which.

The rotation of the shaft |09 is adaptedA is adapted tov support said intermediate upwardly inclined conveyor ||6. In a conventional manner, not'shown in the drawing, there is a similar shaft journaled at the lower end of the conveyor frame ||l6 which also carries sprocket `gears similar to the sprocket gears ||4 and which are interconnected therewith by the sprocket chains H5 to thereby drive the conveyor |||6..

The upright guide plates ||1 are secured in position on the interior edges of the frame elements 9 and are spaced upon opposite sides of the conveyor belt ||'6 for guiding the cut grain or'other`material whichv is transported from the pick-up conveyor to the intermediate conveyor H6 which thence directs the same upon the loading conveyor 65.

Byv the above described construction rotation of the wheel as it is drawn along the ground causes the` movement ofthe three conveyors described above. f

By employing the universal joint ||8 between shafts |09 and |09 as shown in Fig. 4, it is apparent from the drawingsthat the shaft |09 is stationary though rotatable, whereas shaft |09' is rotatable with respect thereto inasmuch as said shaft is .journaled and supported below and upon the under side of frame elements S3-'54. This means that; the conveyor belt will receive power regardless of the angular positioning of said conveyor with respect to thev main body frame of the harvesting machine. While the present machine is particularly adapted for the harvesting of beansyt may be adapted for other products as well.v

The .present harvesting machine has a frame which supports a rst conveyor within the supf porting plates 26, a second rearwardly extending delivery conveyor within the frame elements, 53-54 also mounted upon the first-frame, and in addition a third upwardly inclined` conveyor- ||6, which 'is alsoA positioned within the first frame and arranged intermediate the first and second frames. 'Ihe lower end of the third conveyor is below and adjacent the upper or inner end of the rst conveyor. The upper end of the third conveyor is arranged adjacent andabove the corresponding inner end of the second conveyor. Y

The wheel drives the shaft 3 and gear 4 which drivesA sprocket shaft 6 operating the first' pick-upy conveyor. Sprocket chain |06 inter-r connects sprocket shaft 6 and shaft |09, Fig.' 2. Fig. 4 ilustrates the sprocket chain-'H9 interconnecting shaftsA |09 and 6|. Shaft 6|"and the sprockets 63 thereon operate the second rear, wardly extending" loading conveyor 65. The sprock'et'chain |06 is alsoconnected to sprocket H2v on shaft ||3 for operating the third ntermediate conveyor ||6.

Thus on4 movement 'of the-machine all three conveyors will" be operated simultaneously for picking-up the grain in the first conveyor, trans' mitting the same to the third conveyor whichv in turn transmits the grain to the second con.- veyor which is adapted to unload said grain in any suitable storage .mechanism.

The second conveyor *65 is supportedV by the inverted Urshaped kframe 10 which is mounted upon the rear end of the beam .14 vshown in Fig.

` V2. Sadbearn intermediate its endsis pivoted at 16 upon the swivel 15. The front end of said beam is joinedby aflink |03 to an operating lever 91 whereby the beam14 may be swung to the right or theuleft uponthe swive1 15` in'turn1 7 swivelling the 'secnnd lconveyor 'to the right or left.
